I looked at the Optima turbos 1/4 mile time and ewwww. 14.7? 0-60 in 6.1 or so seconds. So that would put my 0-60 somewhere around there if there was a "good" driver in the Kia.

Its all rumor and conjecture until a run at the track, but the turbo has roughly doubled the horsepower of the 2.8 at 7psi, and cut the 0-60mph time by a good bit.

I really wish it wasn't dark so I knew what kind of BMW it was I raced that time. It had a turbo on it; it was brand spanking new too.
Can't wait to see what the rebuilt trans and front mount with more boost will do
Stock 700r4 will take at least 5-6psi of boost in OD and pulled it to 130mph. Not at WOT though. New top speed by 1mph LOL. Well with the boost valves and vette servo anyway.

willexoIX

Well the new transmission is in; Its beyond my wildest expectations. Its perfect. Little lazy out of the hole, but no more slippage. 3rd gets up there way quicker, 3rd gear was apparently on the verge of going in the other trans. The shifts aren't so firm as to jar your brain, but they are instantaneous. Dana knows his ****.

Got the perfect fluid fill the first time, New Hayden trans cooler, 2 1-2 times larger than the old one and it does a great job, and is supplemented by the fan that comes on with the coolant fan.

New Poly TA bushing really quieted and smoothed things out, And with the past pulling and reinstalling of the last trans I cut the install time down to about 2 hours.

Got the Founders on car adjustable poly end panhard on too and it really helped stiffen the rear.

Ordered the MS2 cpu so I can hook up a knock sensor and really start getting down and dirty with the tuning. I can also re-implement the IAC for starting and add in boost control.

After all that its onto the Hybrid

I would post more pics but the uploads keep failing. Also the IBautogroup app keeps crashing so I have to check threads from the computer. They apparently support the iphone app more....

Funny your trans started slipping on you, I've beaten on mine and it's still holding strong- although I haven't driven my car in awhile. Somehow I managed to push way more pressure through my old motor than you did and both the trans & motor survived. Kinda wish I had held on to that block now...

willexoIX

I killed the first one by leaving the TC locked on a 4-3-4 shift in boost. The second one slipped ever since it went in, because Rubberducky beat on it before I got it. Once it went in I continued to beat the crap out of it but it never let me down. The one I just rebuilt, mannnnnn, what a beast.

Though I was kinda upset about your welding job on those headers, its what pushed me to learn how to weld, so thanks for that. The welds were just too cold with little penetration. Every joint cracked, so I rewelded all of them. Haven't had a leak since.

Though thats water under the bridge anyway so whos keeping track.

Can't wait to get this MS2 cpu today. Going to re-commence tuning today. its nice when the trans doesn't slip to the moon LOL.

I had a guy in a new mustang GT talk smack about keeping the v6 in the Camaro. He had much more respect for me when we stayed nose and nose up to 80 when we let off. I never even asked what motor he had.

Mig and flux. What can I say.

willexoIX

True. I watched my dad do flux core one day. I said F that and went right to gas. Flux core can suck my left youknowwhat, LOL.

Great in a field though when the gas just gets blown away.

Have you used the MS2 CPU Dave? Way better than the MS1. Hands down the best investment I have ever made for this car. Don't know why I didn't start with the MS2 to begin with.

The resolution is awesome. 16x16 tables. And the car actually idled around 450rpms for the first time ever. Before if it dropped under 600 it would want to stall.

I don't know if I am grasping it correctly, but it seems the MS2 has way better control over the engine.

It sounded crazy idling that low too. Was able to take my foot off the pedal and it stayed there idling and never stalled. Eventually I brought the idle up to a usable range, but still.

I imported my VE, SA and AFR tables in, but took pictures of the rest of the settings screens to copy settings as you can't just load your MSQ. Only took about 10 minutes, but then ready to turn the key and fire.

I didn't even have to move any I/O pins.

willexoIX

Well the car runs almost absolutely flawless so far, need to get an intercooler piping kit for $90 bucks, more than enough for my needs. I had it at 12psi, too hot so I backed it down to 8psi, still warm, but doesn't get nearly as hot with the current IC setup.

Just on a 12 mile tuning run, AFRs are stable and steady, Idle is smooth, WOT is crisp and fast with the new rebuilt trans, altogether the last piece of the puzzle is mounting the front mount intercooler.

project89

iTrader: (1)

i have used it i only downgraded because i though something was wrong witht he cpu , when it was actually the settings for my peak and hold drivers

my ms1 tables are 16x16 iirc , i started on the ms1 with ms1 extra so i know it better then the ms2 code

willexoIX

I know the MS1 code better as well but i'm never going back. Too much of a downgrade.

Hey Six, you'll be thrilled to hear this. The misfire wasn't the Megasquirt per se, it was the CPU. I still had the occasional misfire after replacing EVERYTHING. Hasn't done it once yet with the MS2 cpu and I have driven it over 300 miles trying to replicate it and nothing.

So to a point, it was the MS, just not as a whole.

So Dave, if yours ever misfires like mine did, Pop that MS2 cpu back in.

PS, it really only took me about 5 minutes to grasp the code in the MS2, its not much different, just way more stuff, and alot of the variables on the tables( AE, WUE, ETC....) are different; but different in a good way.

willexoIX

These plugs went in at the same time as the turbo. Looks to me like its running good.

Getting my intercooler piping Friday and putting the intercooler in on Saturday. We will see what happens

I've been doing some reading during my downtime at work on the MS3 since it's what I'm going to use for my V12 swap in the Mercedes. MS3 does so much its awesome.

willexoIX

I do have a lead on a roller former TBI 2.8 equipped 89 S10. If I do wind up getting it, thats what the 2.8T will go in and I'll swap the MS2 over with it and start with a MS3 for the 3.4/3500 hybrid.

I might be able to pick it up for less than 300.

Full 3900 swap ftw!

willexoIX

I found 6 brand new Sealed Power hyper pistons with the duroshield coating for the 3400 for $200.

fasteddi

iTrader: (2)

I think that's about what I paid for my 3100s same sealed power ones. Although now that I think about it I think mine were closer to the 160 170 dollar area from summit. I got hastings moly rings to match. Iirc they were arround 70 or 80 bucks For the ring set.

project89

iTrader: (1)

check on ebay u can find piston and ring sets for like 50 bucks each
the engine tech sets are really good and use a kb pistion

Six_Shooter

iTrader: (2)

I approve this message.

willexoIX

I wish I had the money for one around here. Though I might be going salary here soon so that would boost the funds some. I checked around a little while back and they wanted $1700+ for 100k+ miles 3900. I'm going to try to offload the 3100 top end and grab a 3500 top end for $100. Same price I paid for the 3100 top end. But like I have said before, if a great deal for a 3900 pops up; I'm on that like flies on ****.

Better yet, I'll go back over the 2.8 once the 3.4/3500 is done and put the 3100 top on it. Pop the 60 trim wheel on the T3 in that and put a T4 with a slightly smaller exducer AR for slightly quicker spooling.

Has anyone looked at a smaller AR on the T4's for the smaller displacement of the V6's? How small is too small? I would want to start to see boost around 2800 and max 3000rpms if possible. Mark, whats the specs on the beast you just got and when are you seeing boost?

Yea just saw summit has them for $163. Price match FTW.

fasteddi

iTrader: (2)

The ar on the beast I have is .88 single scroll. the exducer on the hot side is 73 mm inducer is 77mm iirc or so. I start to see boost anywhere from 2800 through 3500 but I also have a 3500 stall converter. If your stall converter was lower you may see boost lower. The difference in a t3 to t4 in size is amazing.

Believe me though the turbo I have is a monster and when the boost hits... it hits hard.

willexoIX

Thats close to the specs I am looking for too. I will put a good converter in as well, Not a parts store converter like I have now, though its not that bad.

So the intercooler won't fit where I want to put it without a shoehorn. The inlet/outlets are blocked by the frame rails. BUT if I put a 5* bend on both inwards, they will clear the frame rails, so that's what I'm gonna do. Gotta pull the crash bar off the car and use my friends plasma cutter to cut the center out.

Got RubberDuckys car running great though!

willexoIX

Going to make my own crash bar with angle iron. The mount for the intercooler will be part of the new crash bar.

at the same time i did that i layed the radiator over for a ton more room infront of my engine

willexoIX

Dave, you're going to have to cut a huge *** hole in your bumper to use all of that core, or you'll just be using the center of it. I am sealing mine to the opening so there is no possible way for air to flow around it for maximum efficiency.

willexoIX

Rough mock up without and with the grille. I a DEF running the grille. I am re-using the crash bar, but cutting the hell out of it. Though I am VERY uncomfortable cutting the bottom bolt hole on the frame horns towards the center to clear the in/out of the intercooler. Though I'll never sell the car; still not crazy about it.

But there is no going back now.

project89

iTrader: (1)

its all getting ducted in , i also cut out the front center of the bumper like orrz did , its the same intercooler setup he ran into the 8's

the core is 32x12x4 its a big *** core

project89

iTrader: (1)

ps leave the grill out of it it looks good, gets some mothers aluminum polish and a rag and polish the front of that thing up

willexoIX

Nope. Putting the grille in because of the tractor trailers. Not trying to have a bunch of crap hit it. It'll still get hit by stuff, but it'll be protected from big stuff, animals, children, etc, etc...

I am also getting rad paint and painting the front black. Its getting a stock RS hood again and its going to be a sleeper. Thinking about a blue Chevy logo sprayed on the front though!

The next turbo is getting a silent recirc valve so nobody will see it coming, LOL.

Also thinking of just getting the early 2.8 MPFI badge for the rear bumper to throw people as well. "Yup, its got a 2.8L in it." I'll just leave out the fact that there is a turbo on it Muhahahahahahaha!

willexoIX

**** yeah it is. Good to know your gonna duct it in, should work wonders then. You should also do splitters in the duct to route air across the whole core as well.

project89

iTrader: (1)

dont paint it u will knock about 25% eff out of the intercooler core , ppl have done testing with painted cores and it kills the efficiancy
if anything only paint the tanks

Here is what my intercooler is.
Core Size: 31 inch x11.5 inch x 3 inch

Things pretty big i think. Im sure yours will be large enough for sure.

willexoIX

Mine is 20x7x3. And its beast though. So heavy my dad was checking with a magnet to make sure it wasn't steel, lolol.

Well its mounted to the crash bar. Just have to start trimming tubing to get it finalized. Then I might take it out without the bumper

Not too sure about that one though. Might just take it out when its dark and terrorize the turbo Civics that hang out after dark. One was rumored to be running 16psi (Again, I know this isn't a measure of power but a measure of restriction), and I walked off on him at only 8psi. The look on his face.....

project89

iTrader: (1)

u need some runer between the steel straps and the intercooler otherwise the steel straps will rub right threw the aluminum . get an old bicycle tube and cut it then wrap it around the steel straps were it touched the intercooler and zip tie it inplace

willexoIX

1/4 inch rubber gasket material.

willexoIX

Runs so much cooler now. Barely any temp rise from 30-120mph. Small boost leak somewhere though; I can hear it. I'll look into it tomorrow.

Its quicker too.

fasteddi

iTrader: (2)

Nice. That looks like the first knew cooler I had a few years back. it's about the same size. It worked well.

willexoIX

It works phenomenal. So at 57.2 DC I am only seeing 14ms PWs at roughly 9psi. There has to be a pretty good sized boost leak cause I turned the wastegate past what would have been 16psi and its only making ~9psi/165kpa. I think 15/16psi would probably max the injectors/fuel pump.

The turbo already has shaft play, which doesn't make sense cause oiling is more than adequate and there is no coking of oil. I am currently having a diesel shop hunt down a genuine Garrett rebuild kit for the turbo, because I cant find one. NO ebay rebuild kit will touch this turbo. Even hesitant about Gpopshop.com, though they actually tell you which carbon seal you need. Mine is the one piece dynamic seal.

All the fins are intact and no contact with either housing has been made. Plus its been reliably making 8psi for months.

Got a couple areas of piping rubbing the frame that I need to address today but I have been looking over the datalog I took and all seems well.

project89

iTrader: (1)

im pretty sure u just have the 3 inch thick version of what im running, mines actually about 4.5 thick

willexoIX

Boost leak is gone, now I just need to finagle with the wastegate to get the boost where its supposed to be.

iTrader: (2)

Getting rid of boost leaks is always a good result.

What would be the best exhaust manifold stud kit for these heads? I know the size/pitch, but want to see if anyone has a recommendation?
